Created my first TerminalFour content type

I created a content type for Lancaster University's installation of the TerminalFour CMS that allows users to add a large image as its own block. It has three size options that are gathered using php and the data-* html attribute (which is called in CSS - I find it amazing that you can do that). You can add an optional caption and photo credit too.

I used HTML, CSS and PHP to make this.
